Got a VLT adventure rtf, and invited 2 guildies to join. nothing new, done it 1000ish times befor...

But my friends can't see the invite, but in my "show details" buth of them is awaiting there accept. After 8 houres, only one of the lootspots reset. tryed to invite a friend with the spot that is reset, but now its bugged again and she can't se the invite...:confused:

Status: finishing it, and will make a new VLT to see if the problem happens again.
